-DEMOUNTABLE To all w/rom t may concern.: l

'lde it known that l, JOHN B. KELLY, a citizen of theUnited States, residing at 5958' Washington Boulevard, Chicago, in the countyof Cook and State of Illinois, have invented anew and useful Improvement in Demountable Wheels, of which the following is a specification.

My invention relates more particularly toA demountable wheels of the type employing an inner hub member, an outer hubV memberV adaptedto be telescoped therewith and provided with means for preventing accidental separation of the hub members lone gitudinally of each other, and a key adapted to be assembled with said hub members and operating to prevent relative rotation of the latter when the wheel is 4in use; and my objects, generally statedfaretovprovide an 'improved construction of demountable wheel which shall be simple of constructlon, eco- U nomical of manufacture, easily and quickly removed and replaced, `firmly locked 1n position, and which shall not be subgect to wear impairing its restrailt against its lateral movement on its support. y

Referring to the accompanying drawings igure 1 is a view in longitudinal sectional eration of the hub portion of a wheel conructed in accordance with my invention. ig. is a section taken at the line 2 on'Fig. and viewed in the direction of the arrow.

when assembled foruse, are releasably interlocked with each other to produce a rigid structure, as hereinafter described. The member 8, in practice, would not, by preference, be removable in the demounting operation, with the member 9 which carries the spokes, 'but would be connected with the driving axle, not shown, of the vehicle,in any suitable manner as is well known in the art, when the wheel is av driving wheel, as for example, the rear wheel of an automobile, and when not a driving wheel, as in the case of the front wheel of anautomobile,

axle, as

would be journaled on a stationary or fixed for example, that shown at X, on a rotary axle, not shown.

The member 8, in the construction illustrated, is of an internal form adapting it to -be o urnaled on the shaft X, in accordance with` well lmown practice. Themember 8 is provided at its inner end with an annular beveled surface 11 which forms a frustum of a cone'with its smaller end to,-

`ward the outer end of the member 8, an

annular shoulder 12 by preference being provided on the member 8 adjacent to the inner end of the surface 11. Beyond the beveled surface 11 and spaced therefrom, on

the member 8, are lugs 13 each extending through an arc preferably slightly less than 90 and equidistantly spaced from each other, it being preferred that other lugs 14 spaced similar to the lugs 13 and provided between the tapered surface 11 and the lugs 13, be provided on the member 8 for cooperation with a key and a, wedge-ring, hereinafter described.

The member 9 is in the form of a hollow cylinder to which the spokes of the wheel would be attached, as for example, at the openings 15 toward its opposite ends. The

member 9 near its inner end isL provided internally with an annular beveled surface 16 preferably concentric with the surface 11 and of slightly larger. diameter, between which surfacesy a split-ring 17 is located for .a purpose hereinafter' described. Between the Vtapered surface 16 and the-outer end of themember Q, are lugs Illspaced circum ferentially of the member 9 preferably more than 90', each of the lugs 18Abeing of a `v width circumferentially equal to the width 50 of said-*memberwhen' the wheel is in use, 4though 'they may. be: dispensed with, :if .de--4 60 f ends in diametrically opposed openings 2'1 p inthe rim section a ofthe member l0, this tube containing a plunger 2.5! adapted to be flanges 13. The member 10, which is in the' form of a cylindrical sleeve cut away at diametric'allyopposed sides through arcs of preferably less than 90,leaving curved sec- 'tions 19 connected at one end by a rim :sec

tion 1O",l formsa key for the members 8 and 9, and uponrotating the membeil 9 on the member 8, to a position inA which the 'lugs 13 and 18 aline lengthwise of these members,

after the latter are telescopedrtogether, as hereinbefore stated, may be inserted at its..

' sections 19 into the longitudinally extending channelsl thus afforded between' the ends of the lu'gs 13 andthe ends of the lugs 18, to

.the position illustrated, in which itsnugly fits, the interlocking of the .key 10 withthel lugs .13 and 18 preventing the member. 9 from turning on the member 8, the parts thus formed` and interfitting forming, in' .eecn a breach-lock.

In assembling the member 9,' with the member 8, as; hereinbefore explained, the-1r split-ring 11'?, which is of springy materiaf,

such as steel, and is preferably normally 'of larger diameter than the diameter of the surface l1 with its ends normally 'spaced apart, becomes wedged between the surfaces I 11 'and 16, as represented in Fig. 1, the 'parts of the structure being s'o proportioned that v l 1.member9.. for steadying thel latter in use whenthe ring 17 becomes wedged, as stated,

the lugs 18 will extend in such position'relative to the lugs 13 that When'the. member '9 is rotated tocarry these lugs'into alinement,

with each other longitudinally o`f the wheel hub, ,the outer end'sof-the lugs 18 .will pass the inner ends .'of the lugs 13 but -fltclosely against the latter, this feature of the con' struction 'preventing'any lateral play of the member) on the: member 8 with the manifest advantage, this provisionagainst ,lateral play. being maintained effective, by reason of the "above 'described 'construction under `continuous luse of the w'heel. The lugs .141

are provided forrthe purpose of forming a desirable bearing surface for the inner ends of the -key-mernber 10,to prevent 'canting -s1red.

'll'feans' are preferably provided -on .the l member '10 .f'orpreventing' the latter from' accidentallyworking outhof 'operative position under. the conditions 'ofuse to which, the .wheel-is put, thesjmeansin the construction, illustrated; comprising a tubular member 20 which is secured at its opposite projected at one vend through an open end of the tube 20, through the medium a j coiled spring 23 conned in the tube 20be; 'L

'tween the opposite, closed, .end of the tubei and a shouldered portion 24 of the aplimger, Y

' the latter being provided with a cross-pin 25 vextending through' slots 26 in the tube 20 70l through the medium of which the pperator may retract the plunger 22`into the; tube 20.

` When it is desired, a cap member such as p that represented at 29, may be rovided for 85 the outer end ofthe Wheelihu .1 I The cap member shown screws atthe threaded porx tion 30 into the internally threadedp'ortion 31 of the member-.8 andts, atan annular.

in which .case it is either journaled on an, axle as. 1n `the. construction illustrated, -or

xed on a. stub axle, some means should be 11o 'provided for holding the inner hub member 8 against rotation during the operation of removing the .wheel y Thisl is eii'ectively accomplished, 'in the construction illustrated, by means of a in is adapted to receive a" 'lugl 39 prvided on' i the inner face` of the inner endlof. the hub@- member 8, whenthe member 35 is positioned fon #the spindle-post 36; Aas hereinbefore 112'5 I,

stated, whereby the -member 8 Vis locked against rotation and the outer hub memberfv 9 maybe readily manipulated either asv ember 35 adapted to be ap- 11,5 plied to, and removed from, the adjacent v naaien foregoing that the Wheel may be easily and quickly removed from the member 8 and replaced thereon, and when secured in place,

l is positively locked against rotation independently of the member 8 and against lateral displacement thereof.
